Abstract: This research investigates the physical and engineering properties of soil in Uposhohor, Bogura Sadar, Bangladesh, to assess its suitability for multi-storey building foundations. Comprehensive field investigations and laboratory tests were conducted, revealing that the moisture content of the soil ranges from 17.6% to 34.41%, with an optimum moisture content between 17.6% and 18.4% corresponding to maximum dry densities of 1.73 to 1.81 kPa. The specific gravity values ranged from 2.50 to 2.71, and the coefficients of uniformity and curvature were found to be 11.75 to 15.13 and 0.41 to 1.10, respectively. Cohesion values varied from 8.67 to 21.45 kPa, while the angle of internal friction ranged from 13.34 to 35.62 degrees. The bearing capacity of the soil was determined to be between 280.45 kPa and 1250.31 kPa, indicating a high capacity for supporting building loads. The study concludes that the soil in Uposhohor has sufficient bearing capacity for the construction of multi-storey buildings, eliminating the necessity for deep foundation systems such as piles. It recommends a tailored foundation system along with a monitoring program to ensure the safety and stability of constructions. The findings provide essential insights for engineers and architects involved in designing multi-storey buildings in the area and can serve as a reference for future geotechnical research in the region.
